hi folks,
I'm trying to interleave 2 audio channels into one and encode it into AAC stream. The gst-launch command is like:
gst-launch-1.0 audiotestsrc wave=1 ! interleave name=i ! 'audio/x-raw,channels=2' ! faac ! fakesink audiotestsrc wave=0 ! i.
Then I got below errors
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstAudioTestSrc:audiotestsrc1: Internal data flow error.
Additional debug info:
gstbasesrc.c(2948): gst_base_src_loop (): /GstPipeline:pipeline0/GstAudioTestSrc:audiotestsrc1:
streaming task paused, reason not-negotiated (-4)
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
Freeing pipeline ...
Can someone please give some pointers here? Thanks.
Xin
